tigris

Download and use Census TIGER/Line shapefiles in R

CRAN version: 0.3.3 (updated 5 July 2016)

Dev version: 0.5 (updated 1 May 2017)

tigris is an R package that allows users to directly download and use TIGER/Line shapefiles (https://www.census.gov/geo/maps-data/data/tiger-line.html) from the US Census Bureau.

To install the package from CRAN, issue the following command in R:

install.packages('tigris')

Or, get the development version from GitHub:

devtools::install_github('walkerke/tigris')

In Version 0.5:

• tigris now supports simple features! To load your data as an object of class sf, specify class = "sf" in the function call, or set this globally with options(tigris_class = "sf").

• Historic boundaries are available for states, counties, Census tracts, and block groups; 1990 (cb = TRUE only), 2000, and 2010 boundaries can be obtained with the year parameter in an associated function call.

Basic usage:

library(tigris)

# Basic plot of US urbanized areas

ua <- urban_areas(cb = TRUE)

plot(ua)

# Interactive Leaflet map (requires the leaflet R package)

library(leaflet)

ua %>% leaflet() %>% addTiles() %>% addPolygons(popup = ~NAME10)

Available datasets:

Please note: cartographic boundary files in tigris are not available for 2011 and 2012.
